Critical thinking tests, or critical reasoning tests, are psychometric tests used in recruitment at all levels, graduate, professional and managerial, but predominantly in the legal sector. However, it is not uncommon to find companies in other sectors using critical thinking tests as part of their selection process. This is an intense test, focusing primarily on your analytical, or critical thinking, skills. Some tests are still conducted by paper and pen, but, just like other psychometric tests, critical thinking tests are mostly administered online at home or on a computer at a testing center.

The questions are multiple choice, and these choices and the style of questions are explained in more detail further down the page. The tests will often follow these two common timings:

• 30 questions with a 40 minute time limit
• 80 questions with a 60 minute time limit

Critical Thinking can be defined in many ways and an exact description is disputed, however, most agree on a broad definition of critical thinking, that 'critical thinking involves rational, purposeful, and goal-directed thinking...by using certain cognitive skills and strategies.' An absence or lack of critical thinking skills at times may lead us to believe things which aren't true, because we haven't sufficiently analysed and criticized the information we've received or used this to formulate and independently test our own theories, arguments and ideas. These are all examples of critical thinking skills put into practice. Glaser (An Experiment in the Development of Critical Thinking, 1941) stated that to think critically involved three key parts:

• An attitude of being disposed to consider in a thoughtful way the problems and subjects that come within the range of one's experiences
• Knowledge of the methods of logical inquiry and reasoning
• Some skill in applying those methods

TalentLens' Watson Glaser Critical Thinking Appraisal (WGCTA) is the most common critical thinking test. You can visit their official site here: Watson Glaser . Most other critical thinking tests are based on the Watson Glaser format. More than 90 years' of experience have led to many modifications and improvements in the test.

The Watson Glaser Critical Thinking Appraisal is widely regarded as a good predictor of work productivity and at identifying candidates with a good potential to become managers and occupy other positions as a senior member of staff. The latest edition of the Watson Glaser Critical Thinking Test has improved its validity, appealed more to businesses by focusing on business-relevant topics, switched to the Item Response Theory (IRT) for its scoring, updated norm groups, and integrated anti-cheat measures by having an online retest, which can be used to validate results.

Developed by Goodwin Watson and Edward Glaser, the Watson Glaser test is favored by law firms , keen to measure people's abilities to reason, reach conclusions and know when leaps in logic have been made. Skills which are required in the legal sector. The questions in each of the 5 sections aims to evaluate the candidate's ability to:

• 1. Arrive at correct inferences
• 2. Identify when an assumption has been made
• 3. Use deductive reasoning
• 4. Reach logical conclusions
• 5. Evaluate the effectiveness of arguments

Did You Know

The most recent revision of the W-GCTA was published in 2011 with notable improvements being better face validity and business-relevant items, scoring based on Item Response Theory (IRT), updated norm groups, and an online retest which can be used to validate a paper and pencil test result.

A Critical thinking tests assesses your ability in 5 key areas mentioned above; assumptions, arguments, deductions, inferences and interpreting information. Often in this order. A short paragraph of text a few sentences long or a single sentence is used as a starting point. This passage will contain information which you will base your answer to the question on. Another sentence is then presented to you and you will be asked to judge something about this sentence based on the information in the short paragraph. The five sections are explained in more detail here:

• Assumptions - You are being asked to state whether the information in the second set of text you are presented is an assumption made in the first paragraph. Quite a tricky concept to get your head around at first. In a nutshell, when people speak or make arguments, there are underlying assumptions in those arguments. Here you are presented with some assumptions and are asked to judge if that is being made in the original statement. For example in the statement "only people earning a high salary can afford a fast car," what's being assumed is that fast cars are expensive because only people who are earning a lot of money can buy one, however, what's not being assumed is that people without high salaries aren't legally allowed to buy a fast car. You are asked to choose whether an assumption has been made or has not been made.
• Arguments - You are presented with an argument, such as "Should college fees be abolished?" Regardless of your own opinions and thoughts on the argument, you are then presented with statements related to this original argument. You are asked to say whether the responses to the original argument of "Should college fees be abolished?" make for strong or weak arguments. Arguments are considered strong if they are related to the topic such as, "Yes, many people who would benefit from a college education do not because they cannot afford it. This hurts the country's economic growth." The argument presented is sound, related to the original question. Compare this with a weak argument, "No, I do not trust people who read a lot of books." It is clear that the second argument bears very little relation to the subject of the abolition of college tuition fees. This is not to say that an argument against the original argument will always be a weak one, or that an argument in favor will always be a strong one. For example, "Yes, I like people that read books," is in favor of the abolition as indicated by "yes," but that person's like or dislike of others that read books isn't related, or hasn't been explained how it's related to removing the fees. Carefully considering what is being said, remove it from your own personal opinions and political views to objectively analyse what someone else has put forward.
• Deductions - A few sentences of information are presented to you. Another separate short statement will also be shown to you, which is supposed to represent a conclusion that someone has reached. You will have to determine whether this conclusion logically follows from the information given to you. Can the statement be deduced from the information available>? If so, and without a doubt, then the conclusion follows, if not, then the conclusion does not follow. Your decision must be based on the information given and not from your own knowledge.
• Inferences - A short scenario is described to you, followed by possible inferences. The inferences are short statements. Imagine that these are what people have said is inferred from the scenario. Use your judgement and the short scenario to assess whether what's being said has actually been inferred from the passage and the likelihood of this inference. You are asked to rank each inference as either 'true,' 'false,' 'possibly true,' 'possibly false.' For some proposed inferences there isn't enough information to say either 'true' or 'false' so a fifth option is included; 'more information required.' You can only select one option from the five.
• Interpreting Information - Following a similar format to the previous four sections, a short passage of information and then a series of statements are shown to you. You are asked to judge whether the information in the passage can be interpreted as the statements suggest. The answer options are straightforward here; you either select 'conclusion follows,' or 'conclusion does not follow,' depending on whether or not you believe that the statement can be logically reached from the information given. Again, for this section and all others, you are to base your choice of answer on what you're given, not on any specialized knowledge you might have.

If a watson glaser critical thinking test is used in the early stages of the application process it's likely to be used as a screening tool. This puts some pressure on candidates to meet a minimum pass mark, which will allow them to be selected to go on to the next stage of the selection process. If it's used at a later stage in the process, the results from this will be combined with performance in other assessments, tests, exercises and interviews. All the information you need to answer the questions will be in the test. Below the details of a few companies' critical thinking tests are pointed out.

Here is a list of critical reasoning tests on the market at present, which candidates may be likely to encounter for recruitment, selection or development.

• W-GCTA - The Watson Glaser Critical Thinking Appraisal as it is formally called is the most ubiquitous critical thinking test out there. This is the one that you are most likely to encounter.
• GMAT - The general management aptitude test, used by business schools and colleges test students' critical thinking ability. The critical thinking questions are written in a business or finance context.
• SHL - SHL have produced the Critical Reasoning Test Battery composed of 60 critical reasoning questions with a strict time limit of 30 minutes.
• Cornell - Cornell have developed a critical thinking test to be used in educational environments. The two levels, X and Z, are aimed at children and adults, respectively.
• Area-specific - There are tests which focus on either numerical critical reasoning skills and verbal critical reasoning skills. These tests will ask only numerical or only verbal questions to assess your skills in a specific area.

Here is some general advice to help you perform to the best of your ability for your critical reasoning test.

• No prior knowledge - The key point here is that critical reasoning tests are measuring your ability to think, or the method that you use to reach a conclusion. You should therefore not rely on prior knowledge to answer the question. Questions will be written so that you do not need to know any specialist knowledge to answer the question. For example, you will not be expected to know mathematical formulas or laws of nature and to answer questions with that information. If you are given the formula and its description in the questions, you are expected to use that information to reach the answer.
• Carefully read the instructions - There are 5 sections to most critical thinking tests and each will assess a slightly different skill. Make sure you have read the instructions and understand what it is you are expected to do to answer the questions for this section. There is quite a difference between the Assumptions section and the Deductions section for example. Applying the rules of one to the other would lead to just guessing the answers and making many mistakes.
• Keep your eye on the timer - These tests are complex. You might find yourself fixated on answering one question and taking up a lot of the time you are allowed. Checking how much time you have every so often can help you to more evenly distribute your time between the questions. This is done to avoid spending too much time on one question when that time would be better spent answering more or checking your answers. This time management applies to all tests, but is particularly important with Critical Thinking tests, as many people believe they have such a large amount of time, but underestimate the number of questions they have to answer.
• Logical fallacies - Identifying logical fallacies is key to many parts of this test, and researching the difference between sound and fallacious logic will prove helpful in a critical reasoning test. A fallacy is an error in reasoning due to a misconception or a presumption, and an argument which employs a formal fallacy, logical fallacy or a deductive fallacy in its reasoning becomes an invalid argument. Researching the different types of fallacy (i.e. red herring argument, straw man argument, confusing correlation and causation etc.) can help you spot these in the test and correctly answer the question.

The practice tests that we have cover all of the sections of the Watson Glaser Critical Thinking test and these overlap with many of the variations in Critical Thinking tests produced by major publishers. practice helps to increase your confidence, gives you a chance to learn from your mistakes in a risk-free environment, and can reduce stress before an exam.

The best place to get advice on taking a critical thinking tests is the test publisher's website, for example this one for the Watson Glaser .

If you have already successfully passed a few initial stages of the application process, it's unlikely that companies will focus solely on your results in the Watson Glaser Critical Thinking test when deciding whether or not to hire you. This type of selection by results on one test is more likely if it is part of the early stages of the process. However, towards the later stages the company will look at your results across interviews, group exercises, other aptitude tests and your résumé and will collate all of this information before reaching a decision. If you have been invited to undertake a critical reasoning test then the organisation clearly has an interest in hiring you, let that fact inspire confidence and perform to the best of your ability on your test, good luck!

Watson-Glaser Assessments: Guidelines & Practice Examples

Originally designed by Goodwin Watson and Edward Glaser, The Watson-Glaser Critical Thinking Appraisal (Form AM) was a measurement of “how well you are able to reason analytically and logically.” After their extensive use during World War One, experts increasingly used the tests as a tool to rank and filter individuals in contexts including (but not limited to) education and employment. In this article, we’ll be providing you with an overview of The Watson-Glaser Critical Thinking Appraisal, its test format, and question examples for your practice.

Table of Contents

What is a Watson Glaser test?

The Watson Glaser Assessment (Watson Glaser Critical Thinking Appraisal) is designed by Pearson Talentlens – a part of the famous Pearson education publishing house. The assessment is a quick, consistent, and accurate measurement of the test-takers ability to analyze, reason, interpret and draw logical conclusions from written information .

This critical thinking test has five scales which are the elementary units of critical thinking and reasoning . These five units serve as parameters to measure all areas of critical thinking ability.

The test is administered to appraising adults (16 years and above) with questions of varying difficulty and format.

Watson Glaser Test format

The Watson Glaser Critical Thinking Appraisal is a timed test. It can be administered both online and offline, depending on the company you are applying to.

• For the online version (W-G III), the test is suitable for the unproctored screening of job applicants . Questions are selected randomly from a larger pool of questions called “item bank”. This helps minimize the possibility of cheating due to the fact that there are no applicants having the same set of questions.
• For the offline version (W-G II Forms D and E), applicants have to take the test under supervised conditions .

Upon finishing, applicants receive a percentile score with norm groups either provided by Pearson Talentlens or designed by the company.

Popular test formats are as follows:

• 40 questions – 30 minutes
• 80 questions – 60 minutes

The question distribution in a 40-question Watson Glaser test includes the following:

• Inference – 5 questions
• Recognition of assumptions – 12 questions
• Deduction – 5 questions
• Interpretation – 6 questions
• Evaluation – 12 questions

Watson Glaser test: 5 question types & examples

Five types of questions appearing in the test are

Infer questions

• Recognize Assumption questions

Deduce questions

Interpret questions.

• Evaluate Argument questions

You will find five choices of answers for each inference in the question: True, Probably True, Insufficient Data, Probably False, and False. Your job is to determine which choice best fits the hypothesis.

• True : If you think the inference is definitely TRUE; that it properly follows beyond a reasonable doubt from the statement of facts given.
• Probably True : If, in the light of the facts given, you think the inference is Probably True; that it is more likely to be true than false.
• Insufficient Data : If you decide that there are Insufficient Data; that you cannot tell from the facts given whether the inference is likely to be true or false; if the facts provide no basis for judging one way or another.
• Probably False : If, in the light of the facts given, you think the inference is Probably False; that it is more likely to be true than false.
• False : If you think the inference is definitely False; that it is wrong, either because it misinterprets the facts given, or because it contradicts the facts or necessary inferences from those facts.

Unlike popular aptitude tests where you use solely given information, this test allows the use of specific commonly accepted knowledge or information that practically every person has.

During the past month, managers scheduled for international assignments voluntarily attended our company’s cross-cultural business training workshop. All of the managers reported that the quality of the training was high and focused on valuable work skills that could be immediately applied.

The majority of training was devoted to rules and regulations for doing business in this country. 

A. True B. Probably True C. Insufficient Data D. Probably False E. False

Answer : Probably False

Explanation : Probably False because the training focused on cross-cultural business. It cannot be considered definitely false because the specific course content is not provided.

Practice Example:

Chamonix is one of the oldest ski resorts in France. Last year, the Chamonix-Mont-Blanc Valley authorities introduced a climate and energy action plan, the first in the French Alps. The plan commits to reducing greenhouse gas emissions in the area by 22 percent. Among the proposed measures is a ban on the most polluting lorries using the nearby Mont Blanc tunnel. Climate change will have a major impact on the valley’s main economic activities: less snow on low-altitude ski slopes and the risk of increased pressure on high-altitude ski slopes have been recorded in recent studies. Natural habitats, river patterns, forests, and agriculture might be radically transformed, increasing the likelihood of hazards such as avalanches, floods, and landslides.

Although air quality is a great concern for those living at the foot of Mont Blanc, noise pollution is arguably the most noticeable at a local level.

A. True B. ProbablyTrue C. Insufficient Data D. Probably False E. False

Answer : Insufficient Data

Explanation : The passage does not mention noise pollution, as well as its existence at local level.

Recognize assumption questions

In this question, you are presented with a statement and two choices “ Assumption made ” or “ Assumption not made “. Your job is to determine whether the statement is an assumption taken for granted (Assumption made) or an assumption not necessarily taken for granted (Assumption not made).

We need to save time in getting there so we’d better go by plane.

There is a plane service available to us for at least part of the distance to the destination. 

A. Assumption made B. Assumption not made

Answer : Assumption made

Explanation :

This is assumed in the statement because, in order to save time by plane, it must be possible to go by plane.

While owning a pet can be expensive and is occasionally an inconvenience, it’s a good thing to do if you want to improve your chances of living a satisfying life.

Pet owners will always lead more satisfying lives than those who don’t own pets.

Answer : Assumption not made

From the given premises, we can only see that: if you want a satisfying life, it is a good thing to have a pet. However, having a pet does not definitely lead to a satisfying life. There is no indication to compare the satisfaction between having a pet or not having a pet as a way to live a satisfying life. 

In this type of question, each item contains several statements (premises) followed by several suggested conclusions. For the purposes of the test, you must consider the given statements as true without exception. The question presents you with two options

• Conclusion follows : If you think the conclusion necessarily follows from the statements given;
• Conclusion does not follow : If you think it is not a necessary conclusion from the statements given. 

Since the test requires you to regard given statements as completely true, you have to try not to let your common sense and existing knowledge interfere. You have to stick to only the given statements (premises) and make judgments as to whether it necessarily follows from the statement or not.

One thing to note is the use of the word “Some” in this type of question. It means an indefinite part or quantity of a class of things. It can be either a portion or perhaps all of the class.

Sample: 

Some Sundays are rainy. All rainy days are boring. Therefore …

Some Sundays are boring.

A. Conclusion follows B. Conclusion does not follow

Answer : Conclusion follows

The conclusion necessarily follows from the statements because, according to them, rainy Sundays must be boring.

Damage to roads in the area has made them unsuitable for loads over one ton. These loads are being transported to the capital by air, but as air resources are limited they are restricted to carrying food and medical supplies. Roads cannot be repaired until medical emergencies are dealt with. Therefore, …

Food can be taken to the capital by road.

Answer : Conclusion does not follow

Roads can not be used to transport food in loads over one ton. Food loads over one ton are being transported by air. We are not sure whether food in loads under one ton are delivered by road or anything else.

An interpret question provides you with a short paragraph followed by several suggested conclusions. You must assume that everything in the short paragraph is true, for the purpose of the test. To answer the question, you have to judge whether or not each of the suggested conclusions logically follows beyond a reasonable doubt from the information presented in the paragraph.

You have two answer choices:

• Conclusion follows : If you think the conclusions follow beyond a reasonable doubt (although they may not follow absolutely and necessarily);
• Conclusion does not follow : If you think the conclusions doesn’t follow beyond a reasonable doubt from the facts given in the short paragraph. 

As a rule of thumb, you should judge each conclusion independently from your common sense or outside knowledge.

A study of vocabulary growth in children from ages eight months to six years old shows that the size of spoken vocabulary increases from zero words at age eight months to 2562 words at age six years.

Vocabulary is slowest during the period when children are learning to walk.

Answer : Conclusion does not follow.

The conclusion does not follow because there is no information given that relates the growth of vocabulary to walking.

An accounting computer program, MagicNumber, is Wisdom Software’s biggest-selling product, with its development involving 20% of programmers and 30% of marketing staff. DesignAid, a graphic design program, is the latest offering from the company. It is definitely expected to sell more copies than MagicNumber and will have fewer programmers working on its design, but more marketing staff.

DesignAid will bring in greater profits for the company than MagicNumber.

The paragraph only mentioned that DesignAid is expected to sell more than MagicNumber. This does not necessarily mean that DesignAid uiwll bring greater profit than MagicNumber.

Evaluate argument questions

The question involves distinguishing between strong and weak arguments, as far as the question at issue is concerned. In each question, there is a series of arguments that you must regard as true. Your job is to determine whether or not each of these arguments is a strong or a weak one.

• Argument strong : If you think the argument is strong;
• Argument weak: If you think the argument is weak.

For an objective evaluation of the argument, you must judge each argument independently on its own merit, without the influence of your personal perception.

One thing to note is the use of the word Should. By using Should at the beginning of each question, it means “Would the proposed action promote the general welfare of the people in your country?”

Should young adults in this country go to university?

No; a large percentage of young adults do not have enough ability or interest to derive any benefit from university training.

A. Argument strong B. Argument weak

Answer : Argument strong.

If this is true, as the directions require us to assume, it is a weighty argument against all young adults going to university.

Practice Example 5:

Is it worthwhile for a business to invest in training employees?

Yes, research shows the amount of money spent on training is positively related to profitability.

A. Argument Strong B. Argument Weak

Answer : Argument Strong

The explanation show that business can increase their profit by invest more money on training. This is a direct back up evidence for the claim.
